Module: Interactive Thresholding ()

Description:

Binarization transforms a gray level image into a binary image. This method is used when the relevant information in the gray level image corresponds to specific gray level interval.

This tool allows thresholds to be selected interactively. The current selection is displayed in blue by default over an orthoslice representation with graylevel data as background. This preview can also be displayed in 3D with volume rendering.

Press the Apply button to create the binary output image. A new field is created that is 1 for each value within the threshold interval and 0 for all other field values.

Connections:

Data [required]
Image data the thresholds are applied to. Supported images are HxUniformScalarField3 and HxUniformColorField3.

Mask [optional]
Optional image data used as a mask for thresholding. The image data must be a binary HxUniformScalarField3 with the same dimensions as the input image data. If such a mask is connected, threshold will only be evaluated where mask value is equal to 1.

Ports:

Preview Type

Displays a preview representation of the result. You can choose to display it as a 2D orthoslice, or with a 3D volume rendering. Notice that the 3D display option will not be available if there is a mask connected to the Mask port.

Preview Orientation

This port provides three buttons for resetting the slice orientation: xy perpendicular to the z-axis, xz perpendicular to the y-axis, or yz perpendicular to the x-axis.

Colormap

Choose a colormap to map data to colors.

Preview Slice Number

This port allows you to restrict the range of visible data values. Values below the lower bound are mapped to black, values above the upper bound are mapped to white.

Rendering

Labeled voxels can be rendered either in a transparent or opaque style.

Intensity Range

Specifies the lower and upper values of the threshold interval. Default range is the calibrated data window if set, or the full data range if not.

Color Mask

Choose color to display mask.
